The largest study to date on the early detection of colorectal cancer offers benchmark data for what could be expected from large-scale use of flexible sigmoidoscopy as a screening tool for colorectal cancer. The report, published in the July 6 issue of the Journal of the National Cancer Institute (JNCI), is part of the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial, a randomized, community-based longitudinal study evaluating the effectiveness of cancer screening tests on site-specific mortality.
"In our opinion, we now have published important and valuable baseline data on the use of flexible sigmoidoscopy within a large and randomized group of participants," said Joel Weissfeld, M.D., M.P.H, lead author of the study and associate professor of epidemiology, University of Pittsburgh Graduate School of Public Health. "The findings reveal trends and patterns by gender and age that one may expect to see in a flexible sigmoidoscopy intervention targeting the general U.S. population," added Dr. Weissfeld, who also is co-leader of the cancer epidemiology, prevention and control program at the University of Pittsburgh Cancer Institute.
During flexible sigmoidoscopy (FSG), a doctor uses a lighted scope to examine the inside of the large intestine from the rectum through the descending colon, where most colon polyps develop.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
